You can define a vertical line in SLD like this:

               <CssParameter name="stroke">#333333</CssParameter>
               <CssParameter name="stroke-width">1</CssParameter>

There is no definition in xml for the place of that vertical line. I am making a solution for OpenLayers like in [1] but cannot figure out, how to place the vertical lines across the long line that goes horizontally.

Adding to OpenLayers goes similar to:

var format = new OpenLayers.Format.SLD();
    url: "yoursldfile.sld",
    success: sldparser
function sldparser(req) {
    sld = format.read(req.responseXML || req.responseText);
    styles = sld.namedLayers.interpreted.userStyles[0];
    building_vec.styleMap.styles.default = styles;

I would like to add the vertical lines to places, where the continuous line makes a tilt to new direction.


How to tell the place of vertical lines in the combo of Openlayers and sld?

More specifically:

How to tell it is in the turning point of straight line?

With picture:

I want the vertical "railroad hatches" to appear only in places, where the "railroad" changes direction. [2]

The vertices function might help you, as documented in the GeoServer manual. I used this to show cadastral survey points.
